Redmi Note 7

[Discussion] distorted audio recording at concerts/night clubs

this is how Redmi note 7 records audio in loud place:   total disaster, noise, distortion. Samsung, Iphone, PPTV King 7 record audio ideally in the same conditions: (sample on King 7). Can developers please test and improve microphone parameters in /system/vendor/etc/mixer_paths_wcd9326.xml
path name="handset-dmic-endfire"

ctl name="ADC1 Volume" value="12" /
ctl name="ADC3 Volume" value="12" /

some guy on forum suggested to write "6" there for better sound, i could not test it because of no root rights. Ideal would be: in case of low volume in recording place - AGC rises mic sensitivity (currently recorded audio is silent, I must add volume on speakers to the maximum to hear something). In case of loud/bass music mic sensitivity goes to the minimum, to avoid distortion.  Just the way autobrightness works for the screen, Automatic Gain Control

This Bug happen in al Redmi Series, and was never fixed by Xiaomi. On the Note 4x i tried many Rom Versions and non of them fixed the Recording Problem
Other Brands can this much, much better. If this can not be fixed by Software then this was the last Xiaomi Phone for me, there are enough Alternatives on the Market who can also record a Concert or in loud envoironment.

maigonis: yes i installed last gcam mod by Bulkin, and will try next time. But i don't think loud audio will sound better, slobodan_boco commented that Gcam also distorts . Gcam uses stock video procedures, it improves only photo part

forum guys recommended to try sticky tape to make microphones less sensitive, but this is funny of course, not a workaround we were waiting for

Today it is possible to build mobile phones so that a video recording can be made with proper Sound.
or does xiaomi think differently? only selling a lot of Phones ??
